Embodiment Construction
[0021]The embodiment of the present invention is explained in detail in the following.
[0022]The flame-retardant polyolefin resin composition of the present invention (hereinafter to be simply referred to as “the resin composition of the present invention”) characteristically contains the following component A-component D and is substantially free of a halogen atom:
[0023]Component A: a thermoplastic resin having a carbonyl oxygen atom in the molecular skeleton
[0024]Component B: a polymer alloy containing an ethylene component and a propylene component
[0025]component C: a modified polyolefin polymer containing an acidic functional group and having a weight average molecular weight of 10,000-80,000
[0026]component D: an inorganic metal compound.
[0027]As used herein, by the “substantially no halogen atom” is meant non-use of a substance having a halogen atom in a molecule as a constituent element of a composition (constituting material). However, a halogen atom detected in an ultra-trace...
